摘要： PROBLEM TO BE SOLVED: To improve penumbra in a short-range region without being accompanied by increase in costs, increase in penumbra in the outside of the short-range region, and increase in burden imposed on an operator, in a particle beam treatment system using a scanning irradiation method.SOLUTION: A particle beam treatment system comprises an irradiation compensator 101 targeted for a short-range region composed of an energy absorber 302, a first collimator 303, and a second collimator 304. The irradiation compensator 101 includes an attaching/detaching mechanism for the energy absorber 302, the first collimator 303, and the second collimator 304. The first collimator 303 is disposed in an upstream side where the beam diameter is small to help restrain the breadth of the compensator 101, thereby contributing the size reduction and weight saving of the compensator 101. The second collimator 304 is disposed in a downstream side, thereby contributing to the improvement of penumbra.

摘要： PURPOSE:To measure plate thickness to constant distance from a tank side plate by rotating a wheel made of a magnet on the tank side plate in an attracting state, and allowing a forward, a sideward, and a slanting run of ball caster provided to the front wheel parts of a running car. CONSTITUTION:The running car is prevented from leaving an internal wall surface by bringing the wheels 7 made of magnets into the internal wall surface, and the running car moves forth along the wall surface when rear wheels are driven by a motor. A measuring instrument 2 moves in the right-left direction of the running car to measure the thickness of a plate to the width size of the running car during the forward run. Two ball casters are provided to allow the running car to move forth stably and are movable in any direction, and the running car runs copying the wall surface even if there is a projection or recess of the wall surface.

摘要： PURPOSE:To run a running car so that even if there is a step on a floor surface, the car gets over the step sutomatically by providing a elevation mechanism which elevates the front end of the running car. CONSTITUTION:The elevation mechanism 4 equipped with upward/downward movable ball casters is provided to the front part of the running car 1. The rotation of a driving motor is transmitted to bevel gears 8 and 9, a shaft 10, and a chain wheel 11 to move a chain 12. The rotation of the chain wheel 11 is transmitted to a sliding shaft 13 through the chain 12 to move up and down a sliding frame 14. When the driving motor rotates clockwise, the sliding shaft 13 rotates counterclockwise to lower the sliding frame 14, so ball casters are pressed against the floor surface to elevate the front part of the running car.

摘要： PURPOSE:To autonomously select one from among packages by multiplex- connecting the clock outputs of plural clock supply packages, and providing a clock output selection control circuit. CONSTITUTION:All the clock supply packages 11-16 are not always packaged. It is assumed that only the clock supply package 12 is packaged, and the package 14 is newly packaged, for example. Since the control signal of an output gate 104 comes to earth by the package 12 at that time, the output is prohibited, and a reception package 10 operates by the clock from the package 12. When plural clock supply packages 11-16 are packaged in the same way, other outputs are prohibited excluding one output. Thus, one package can autonomously be selected from the clock supply circuit on which the packages are arbitrarily packaged.

Further, the zuxiliary wheels 7 have their bottom parts over the front wheels. The auxiliary wheels 7 are not used in a general run wherein the front wheels 4 rotate, but get over a step, etc., when reaching where the step is formed. Thus, the truck continues to run and the front wheels 4 also get over the step.
